Quick Overview

Why does BRS recommend this?

The Hanna Phosphate checker is an awesome little tool that will give you accurate easy to read results. If you have bad eyes or have a hard time with color change test kits, the digital read out on the Hanna checkers is super nice and easy to read. The biggest key with Hanna checkers is keeping the vials nice and clean for consistent results.

Three simple steps to results. The Hanna Phosphate Checker bridges the gap between simple chemical test kits and professional instrumentation. Accurate, affordable and easy to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Hanna Phosphate Checker, press the button and read the results. Done.

This was my first HANNA checker purchase. Ive been hearing all the rage about these for a while so i finally tried. Very east and simple to use. Less then 5 minutes to test and get results. Definitely will be trying a few other HANNA checkers now.

Not sure why Hanna doesn't just Discontinue this product even though they know it's more suited for "Fresh" water than marine usage. I've owned this for 6 months and never had the digits read above 0.00 ppm! Had the signs apparently of having phosphates with algae growing constantly on my glass! Went and purchased RedSea's Phosphate test kit and Salifert's test kit just to make sure and too my surprise not only I had phosphates present in my reef tank but that the results showed RedSea 0.8 ppm Salifert 0.07 but yet my Hanba HI-713 can not detect these units! I emediatly called Hanna Headquarters in Smithfield Rhode Island and to my surprise, they told me that the HI-736 ULR which is the "Ultra Low Reading" test kit would be more suitable for me, which really indicates that thier aware of this problem! IMO, maybe they just never made an attempt to recall this model of kit in in order to save tons of money they just went ahead and slapped on the "Fresh & Marine " label and kept it as is but clearly if you don't see a "Fish" label in front of your handheld with the "Marine" label as well than it's not suitable for Marine! Unfortunately this problem is not going away! Reefers Be Advised, purchase the ULR instead!

Hanna Phosphate Low Range Colorimeter works well . Fast and accurate

Great.. packaging needs improvement.By Yus on 9/26/2016

The product it's great and easy to use. Take away from having to match colors. However, the packages the reagent comes in need to be replaced with a scoop method because it's hard to get all the power out of the packages.

Unsure of accuracyBy Markon 9/3/2016

Mark wouldn't recommend this product to a friend

Iva had this a couple weeks now and have yet to get a reading above 0.00 after 4 tests. I run hc gfo but should still have some phosphates right?

Really only 6 testsBy Jaimeadamson 7/15/2016

Jaimeadams wouldn't recommend this product to a friend

I am disappointed with the fact that it only comes with enough regent for 6 tests. Sure the digital read out is awesome and very helpful, but I really feel that for the price I should be able to test more than 6 times before having to give them more of my money

I hate trying to match colors on tests (ok, I'm also slightly red-green colorblind so that doesn't help!) and this makes it so much easier. Doesn't come with very many test packets so if you'll be doing a lot of testing you'll want refills but they're pretty inexpensive.

Problems with the light sensor the minute the 6 month warranty was up. Randomly worked and then completely dead. Tech support offered up $95/hour service or they said I'm welcome to order a another from them. Don't think so. The results I was able to get when it worked were extremely varied and I couldn't stand trying to get all the powder out of those tiny packets. Need to rethink design on those. Not pleased unfortunately.

Great Checker By KerryFon 3/29/2016

KerryF would recommend this product to a friend

One star off for those silly packets for the reagent. Works well and seems very accurate. Lid seems to have a hard time staying closed with a vial in it the checker...no big deal really.

Nice for Accurate Low Range TestingBy Michaelon 3/18/2016

Michael would recommend this product to a friend

Like many other Hanna checkers this product takes the guess work out of phosphate testing. I have a special loathing for trying to decipher color coded phosphate test kits and this helps me solve that issue. I had to take 1 star off because getting the power into the vial is brutal, and I mean brutal.

It works, just have to get use to the reagents.By jayon 3/5/2016

Good too have two vials. One to set the checker, the other one to have the reagent all ready mixed.

Save your money. I get more accurate results using API phosphate test and its significantly less money. Measures ppm just like API however the Hanna checker shows 0.00 and API shows 0 to 0.25 ppm. Even contacted Hanna to see if it was broke and their first response was to buy the HI736. So they seem to be aware that it's junk. Also, once you open the box it's yours. Bulk reef supply does not except returns on opened items. A little hard to consider buying a second piece of equipment when the first one doesn't work as it should. Also bought the HI758 calcium checker that works flawless. Watch the YouTube video as the instructions are not clear.

Product Questions

I see on here that some users suggest buying the hi736 instead. Which one will work best to determine your overall PO4?

Question by: Justin on Jun 3, 2016 9:26:00 AM

Great question!
We personally use the Phosphate low range in house as it is accurate enough and we do not need to convert the reading from Phosphorous to Phosphate. While the Ultra Low range will give extra decimal placed to your answer We find this is not the most important. Feel free to let us know if you have any further questions!

Does this meter require periodic calibration with some kind of calibration solution?

Question by: Eric on Jun 19, 2014 8:50:00 PM

Hi Eric,
One of the first steps every time you test is to zero out the meter, then you add reagent and test the actual sample. This is done every test but It does not require any sort of extra calibration procedure on top of that.

Designed to work with HANNA's powder reagents Uses 10 mL glass cuvettes.

Small Size, Big Convenience

Weighing a mere 65 g (2.3 oz.), the Checker®HC easily fits into the palm of your hand or pocket.Use for quick and accurate on the spot analysis. Single button operation: Zero and Measure Operated by a single AAA battery.
